UK firm finalizes $18 million deal for renewables in Nigeria
UK-based Konexa has finalized a deal that will see Climate Fund Managers and Microsoft’s Climate Innovation Fund invest $18 million to establish Nigeria’s inaugural private renewable trading platform and provide renewable energy to Nigeria Breweries.
Hydrogen batteries vs. lithium-ion batteries
Researchers in Australia have compared the technical and financial performances of a hydrogen battery storage system and a lithium-ion battery when coupled with rooftop PV. They evaluated two commercially available systems – LAVO and Tesla Powerwall 2 – and found that the lithium-ion battery provides better financial profits, whereas the hydrogen battery offers more battery lifespan for long duration of energy storage.
U.S. Boiler unveils hydronic heat pump for residential applications
The US-based manufacturer said its new heat pump system has 5-ton capacity and a coefficient of performance of up to 3.95. It uses difluoromethane (R32) as the refrigerant and relies on DC inverter enhanced vapor injection (EVI) technology.
US energy storage sector booming, says Wood Mackenzie
Lower costs, better supply chains and steady demand are driving an energy storage boom in the United States, according to a new report from Wood Mackenzie.
LG presents residential air-to-water heat pump
The system uses difluoromethane (R32) as the refrigerant and has reportedly a seasonal coefficient of performance of up to 4.69.
Schneider Electric, Mainspring offer multi-fuel microgrid solution
Schneider Electric’s EcoStruxure Microgrid Solution can be paired with Mainspring Energy’s Linear Generator to produce and store carbon-free energy for continuous use.
Electrolyzer prices – what to expect
In addition to the cost of electricity, the price of hydrogen depends largely on the up-front investment cost of the electrolyzer. The lower the full-load hours, the greater the impact. Analyst BloombergNEF (BNEF) sees a number of different possible pathways for the market to develop.
Israeli startup develops PV-driven cooling system based on compressed air
Storage Drop has secured a grant from the European Union to develop its PV-driven cooling system technology for low temperature environments. The system is based on compressed air energy storage technology and a hydraulic isothermal compressor with a water pump that compresses the air in an isothermal process.
Hybridizing thermoelectric generators with photovoltaic ground-source heat pumps
Researchers in South Korea have analyzed the feasibility of using thermoelectric generators in combination with residential solar-assisted ground-source heat pumps and have found that the thermoelectric devices may act as a suitable power source for data loggers and other sensors in a building system.
Zen Energy starts building 111 MW/270 MWh battery in Australia
Australian renewable gen-tailer Zen Energy is set to build the second-largest battery energy storage system in the state of South Australia, in a move that is expected to improve the reliability of electricity supply.
